8 Claims. CL 229 69) The invention relates to pocket envelopes andmethods of making the same, and more particularly to a pocket envelopewhich may have either one or a plurality of pockets and which may be imade either singly, or in groups or clusters, on

usual printing presses.

Single and duplex pocket envelopes are widely used by religious or otherorganizations as a means through which collections or contributions 19may be made and collected; but such pocket envelopes heretofore usedhave required special folding and gluing machinery to be used in theirproduction; and have always been made in single units, which are thengathered together and l packed, for distribution by the recipientorganization to the donor-user.

Accordingly, the cost of making and packing such envelopes is highbecause of the special equipment involved; and individual envelopes ofzo the group packed together frequently become disarranged or lostduring the period of time, usually one year, through which their use isintended to extend.

It is therefore an object of the present inven- 25 tion to provide animproved pocket envelope construction which may include either one or aplurality of pockets..

lt is a. further object cf the present invention to provide an improvedpocket envelope construction which may b'e readily made in aninexpensive manner upon usual printing presses.

It is a further object of the present invention to provide an improvedpocket envelope construction having either one or a plurality ofpockets,

which envelopes may be grouped or clustered together in an initiallyjoined relation adapted for ready detachment of individual envelopeswhen and in the order desired; and a plurality of which groups orclusters of envelopes may be assembled together in calendar or bannerform.

And finally, it is an object of the present invention to provide newmethods of making single or duplex, individual or clustered pocketenvelopes from sheet material on usual printing presses,

which methods do not involve any special folding operations, and whichonly involve simple operations that may be readily and inexpensivelycarried out on the usual printing presses.

'Ihese and other objects may be obtained by the articles, products,envelopes and the like, hereinafter described in detail and claimed,preferred embodiments of which are shown in the drawing, which may bedescribed in general terms as including in pocket envelope construction,a sheet of paper or other fibrous material having a of a sheet of gummedpaper;

gummed or adhesive surface, a zone of said surface being de-adhesitized,a second sheetof paper or other fibrous material sealed laround itsperiphery to said gummed sheet .and''having a slit therein forming aflap opposite a gummed portion of said gummed sheet and having anotherportion adjacent to the flap opposite the de-adhesitized portion of saidgummed sheet; and said improved products may be made by the improvedmethods hereinafter described in detail and claimed, preferred steps ofwhich are diagrammatically shown inthe drawing, and which may be statedin general terms as including in a method/ of making pocket envelopes,the steps of deadhesitizing a portion of a gummed or adhesive surface ofpaper or other fibrous material, preferably applying a thermo-plasticmaterial to portions of said sheet surrounding said de-adhesitizedsurface, and sealing a second sheet of paper or other fibrous materialto the thermo-plastic material on said gummed surface preferably by thecombined action of heat and pressure.

The material 18 applied by this printing operationis a thermo-plastic material and may be a mixture` of ve parts of resin,one part of glycerine and four parts of honey. However, it is understoodthat the thermo-plastic material 18 may comprise other materials` orother proportions of the said materials.

'I and 8.

The paper sheets 19 before .being sealed to the witha plurality of diecut slits 20 forming flaps-'20a therein, which flaps y"when the sheets19 are conglutinated to the sheet 15, are opposite the gummed zones 16aon the sheet 15. i l

The conglutinated sheets are then passed through a printing press toprovide printed material 21 thereon, asshown in Fig. 9, it beingunderstood that this printing operation may be performed upon the sheets19 either before or after the sheets 19 are sealed'to the sheets 15, andeither before or after the slits 20 are provided therein.

The conglutinated sheets may then be again passed through a perforatingmachine or a regular printing machine to perforate the same at v22 so asto divide the sheet intova plurality of duplexr pocket envelopes 23clustered or grouped together envelopes for special purposes.

The ap 20aon each side of the duplex envelope 23 may then be vturned back and acoin or other contribution may be inserted in each vpocketofthe envelopeformed between the outer sheet portions 19 and the de-adhesitized zonesof the center sheet-'15. Thereafter, the inner surface of each vflapv20a may be moistened and pressed against the gummed zone 16a to sealthey pocket envelope.

1t is to be understood that the above method of making the duplexenvelopes may be carried out by applying a liquid gum instead of athermoplastic materiall at the zones 18 and then sealing the sheets 15and 19j together while the gum is still moist. Likewise, moisture may beapplied to the gummed sheets l5 at the zones 18 and the sheets 19 maythen be sealed to the sheets 15 while the gum is still moist. However,such steps involve more complicated printingV operations than isencountered when a thermo-plastic material is utilized, because the useof thermo-plastic vmateriaal permitsl the sheets 15 and 19 to beconglutinated at tli'e zones 18 by the application of heat and pressurewithout .theexternal applicavtion of additional moisture or other fluid.

Moreover, it is to be understood that the sheets l5, instead `of beinginitially gummed throughout and then having sones thereofde-adhesitized, may be gummed by omitting applying gum at the zones 17.However, such procedure is also complicated and 'the improved pocketenvelopes may y be more easily and inexpensively made by using fullgummed sheets and de-adhesitizing zones thereof.

It is clear, that when it is not desired to produce duplex pocketenvelopes, that single pocket envelopes may be made by carrying out themethod described above, utilizing a sheet gummed on one side only andthen conglutinating asingle sheet thereto after zones of the gummedsheet have been de-adhesitized.'

It-is likewise to be understood that either single or duplex-pocketenvelopes may be made individually if desired, rather than in groups orclusters, or maybe made in groups or clusters and thereafter severed toprovide an individual duplex -pocket envelope 23" as shown in Fig. 11,or an inzones 18 of the gummed surfaces of the sheets isor 15, with thenaps 20a adjacent a r'emaining` gum f zone 16a.

The duplex pocket envelopes 23' may be printed with any desired copy, asdescribed above, and may be readily sealed by moistening the `linnersurfaces of the flaps 20a, which when closed stick to the gummed zones16a. Y

Likewise, the single pocket envelope 23a comprises a sheet 15 gummed at16 on one side only and provided with a de-adhesitized zone 17 and athermo-plasticized zone 18, a single cover sheet 19 being conglutinatedto the thermo-plasticized zone 18 of the gummed sheet 15. A flap 20a isprovided in the sheet 15 by the slit 20, which lflap 20a is opposite agummed zone 16a. in the sh'eet 15.

Accordingly, the improved method provides an inexpensive manner ofmaking single or duplex individual or clustered pocket envelopes fromsheet material on usual printing presses without involving any specialfolding or other operations.

Likewise, the improved single or duplex pocket envelopes, in eitherindividual or grouped or clustered form, may be used for makingcontributions in a sure and safe manner without loss of contributionfrom the envelope and without directlyv moistening a gummed surface, itbeing necessary only to moisten the ungummed flaps 20a for sealing theimproved envelopes.
